Is it possible to do so? I am spawning infinite objects (a second apart using timer.performWithDelay) and using (transition.to) to get a random location for the object to go but when a new object spawns, the function performs on that object and stops moving the old object. I put the objects in a table and I wanted to try to see if the function could access all of the objects so they wouldn’t stop moving if a new one spawns. Is there an easier way to keep the objects moving?
Can you show us your code?

You’re running into an issue with scope. I’d suggest going through the tutorial below, and attempt to re-create your desired mechanics based on the methods detailed within:
https://coronalabs.com/blog/2015/06/16/tutorial-scope-for-beginners/
Also, I don’t see where you are increasing your “i” variable, which means that you are constantly creating a “circle[1]” object, instead of (I believe) new circle objects.
